COP-WINDING MACH-iNE.

SPECIFICATION forming part of Letters Patent No. 576,355, dated February 2, 1897. Application filed October 16,1893. Serial No. 488,305. l'No model.)

To all whom it may concern:

Be it known that I, SIMON W. WARDWELL, J12, a citizen of the United States, residing in Boston, Suffolk county, Massachusetts, have invented certain new and useful Improvements in Cop-Vindin g Machines, of which the following is a specification.

In the machine for winding cops for which Letters Patent were issued to me August 2, I0 1892, No. 480,157, the thread, cord, or yarn is laid in parallel spirals, and each revolution of the cop is accompanied by an increment of motion that causes each coil of thread to be laid at a point on the periphery of the cop back of or beyond a previous coil, the object being to lay each coil exactly parallel and close to such previously-laid coil.

My invention consists in certain devices,

which I have provided whereby to vary at will the extent of the independent motion of the holder in respect to the guide and in order to adapt the machine to produce perfect cops whatever may be the variations in the character of the thread or the diiferences in the size or the effects resulting from any causes, as illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a cop-winding machine embodying my improvements. 3o Fig.2 is an end view. Fig. 3 is a plan; Fig. 4:, a diagram illustrating the arrangement of the gears.

The machine is provided with a holder 5 for the cop or cop-tube, which holder, as shown, is the end of a shaft a, driven from or having near the opposite end a driving-pulley?) and carrying a toothed wheel 6. There is a threadguide 8, which, as shown, consists of an arm having an eye or notch for the thread and 0 hinged to swing to and from the cop-holder, so as to always lie upon the surface of the cop and deposit the thread in exactly the position where it is to remain, and this thread-guide is reciprocated the length of the cop in any suitable manner.

As each coil of the thread must be laid back or forward of one previously laid, so as to be absolutely parallel thereto at all points, it is necessary, as before described, to retard or ad- 50 vance the movement of the guide or turn the holder and cop at each revolution, so that the eye of the guide as the thread is laid at the extreme end of the cop shall deposit the same not directly on the thread previously laid, as would be the case if the guide reciprocated once to each complete rotation of the holder, but the thickness of a thread in advance or back of that previously laid, all as set forth in the Letters Patent before referred to. To attain this end with threads of different char- 6o actors, the machine is provided with means for varying the extent of the varying movements of the holder and guide, which means,

as shown, consist of certain adjustable speedgearing at some point between the holder and the guide.

As shown, the thread-guide is pivoted to a sliding bar 9, moving in suitable guides and carrying a pin 10, which enters the slot in a cam 12, carried by the shaft a, but turning thereon independently thereof. The cam is provided with a gear 13, which engages a pinion It on a shaft 18, carrying a fricti0ndisk 17, the edge of which engages the face of a friction-cone 16 on a shaft 19, carrying a pinion 15, that gears with the Wheel 6. By this arrangement of speed-gears with the disk 17 bearing on the cone at its center, the holder will reciprocate once to each rotation of the holder, as in ordinary winding -n1a- 8o chines; but by shifting the position of the disk to bear on the cone at one side or the other of the center the speed of the gearing is varied so that the holder will turn more or less than a complete revolution to each reciprocation of the holder.

To maintain the frictional contact of the friction-gears at all points of adjustment, the shaft 19 of the cone-gear is carried in aframe I, swinging upon the shaft a. and carried toward the disk by a spring 0.

Different means may be employed for shifting the disk 17, or the drum might be shifted instead. As shown, the shaft 18 is provided with an arm 20, in which turns a feedscrew 5 21, that passes through the disk and the turning of which will slide the disk in one direction or the other.

It will be evident that by the use of said adjustable friction-gears it is possible to se- I00 cure such minute adjustments as will secure any desired fractional difierence between the movements of the guide and the holder and the perfect formation of cops from threads of different qualities, kinds, or sizes and under all circumstances, and that most perfect adhesion and certain action and accurate adj ustment is had by gears upon substantially parallel shafts, with means to force one toward the other.

It is often desirable to alter the relation of the thread-guide to the holder or its supporting-shaft. I therefore provide for adjusting the guide laterally, as, for instance, by varying the position of the guide and the sliding bar 9. As shown, the said bar is in two connected parts, one the part 9", carrying the pin 10 and connected with apivoted arm 23, which is connected by a pivoted link 24 with a block on the other section. The pivotal. bolt 26 of either or both sections may be adjusted vertically in a slot 00 to vary the extent of lateral movement of the section 0 or to shift the guide more or loss to one side or the other.

Instead of securing the driving-pulley 1) directly to the shaft 5 it may be thrown into or out of connection therewith by a frictionclutch of ordinary character and operated by a lever 40, connected by an arm il with a strap on an eccentric 42, dotted lines, Fig. 1, on a shaft rocked by a handle 48.

Without limiting myself to the precise construction and arrangement of parts shown, I claim as my inventiou- 1. The combination with a cop shaft and holder, thread-guide, and mechanism imparting rotation to the holder, and the cam and connections for reciprocating the guide, of a friction-disk connected with the guide-reciprocating mechanism, and friction-cone connected with the cop-shaft, and adjusting devices for changing the relative longitudinal positions of the disk and cone, substantially as described.

2. The combination in a cop-winding machine, of a cop-holder, rotating shaft for driving theholder, a cam operating independently of the shaft, a guide operated by said cam, a friction-disk and friction-cone between the cam and the holder to rotate the former independently of the shaft, and means for adj usting the relative longitudinal positions of the disk and cone to vary the extent of the independent movement of the cam, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
